annextimelog (atl) is a cli time tracker and logbook made by nobodyinperson. It uses git-annex to store and sync data. atl has a loosely similar usage to timewarrior but improves on many of its pain points:

• tracking of simultaneous events
• conflict-free syncing
• more powerful tagging system
• more powerful search
• more output formats (JSON, hledger timeclock, ...)
• a more sophisticated event specification language

annextimelog is also an experiment how useable git-annex is as a backend for syncable application data storage. While first sounding silly, it works very well.
